Abstract
The cell surface markers on the leukemic cells of 76 patients with adult acute myeloid leukemia (AML) have been analyzed by indirect immunofluorescence, and the presence of CD56+ leukemic cells was detected in ten of these patients. Four of these 10 CD56+ AML patients developed extramedullary myeloblastomas and in two of them an intracranial myeloblastoma. In contrast, in the remaining 66 CD56- AML patients, only one patient developed a myeloblastoma formation of the subcutaneous. It may be that the CD56 antigen which is an isoform of the neural cell adhesion molecule (NCAM), expressed on neurons, satellite cells of skeletal muscle cells, and on stromal cells, binds these tissues by a homophilic mechanism. CD56+ leukemic cells are capable of invading and of surviving in extramedullary tissues, where they proliferate and develop into a myeloblastoma. Because of this possibility, CD56+ AML patients should be carefully monitored for signs of myeloblastoma formation.Entities:
